Most professional boxers are still learning their trade at 19. A handful were already world champions.
Wilfred Benítez famously won a world title at 17, Mike Tyson became heavyweight champion at 20 and Manny Pacquiao had already collected the first belt of an extraordinary career before his 20th birthday. There is now another name in the conversation.
Mexican fighter Camila Zamorano won the WBC interim atomweight championship at 17 years, five months and 16 days in June 2025, with the WBC recognising her as the youngest world champion in boxing history.
That comes with a caveat. Zamorano initially won an interim belt, while Benítez won the full WBA junior-welterweight championship at 17. So if we are talking specifically about full major men’s world titles, Benítez still owns one of boxing’s most remarkable records.

1. Camila Zamorano
Age: 17 years, 5 months, 16 days
Camila Zamorano was still 17 when she beat Mika Iwakawa in June 2025.
The Mexican prospect won the WBC interim atomweight title, becoming the youngest female world champion recognised by the organisation. The WBC has since gone further, describing Zamorano as the youngest world champion in boxing history.
She has since become the full WBC atomweight champion and, as of October 2026, remains unbeaten.
The interim detail is worth remembering when comparing records across eras, but winning any recognised world championship at 17 is ridiculous.
2. Wilfred Benítez
Age: 17 years, 5 months, 24 days
For decades, nobody really came close to this one.
Wilfred Benítez was just 17 when he challenged Antonio Cervantes for the WBA junior-welterweight championship in March 1976.
Cervantes was an established champion. Benítez was a teenager. Benítez won by split decision.
He became the youngest male boxer ever to win a major world title, a record that still stands half a century later. The WBC continues to recognise him as the youngest men’s world champion in boxing history.
The craziest part is that this was not some career peak he never matched.
Benítez later became world champion at welterweight and super-welterweight, defeating Carlos Palomino for his second title at only 20.
3. Cesar Polanco
Age: 18 years, 2 months, 18 days
Cesar Polanco does not have anything close to Benítez’s name recognition, but his place on this list is extraordinary.
The Dominican fighter travelled to Indonesia in February 1986 and beat Ellyas Pical by split decision over 15 rounds.
That made Polanco the IBF junior-bantamweight champion while he was still only 18.
His reign did not last. Pical won the rematch later that year and reclaimed the championship.
Still, Polanco had already done something very few boxers in history have managed before turning 19.
4. Ratanapol Sor Vorapin
Age: 18 years, 6 months, 5 days
Ratanapol Sor Vorapin was another teenage champion who arrived without much global attention.
The Thai fighter beat Manny Melchor by split decision in December 1992 to claim the IBF minimumweight championship.
Unlike some of the very young champions on this list, Ratanapol did not disappear immediately afterwards.
He built a lengthy reign, made numerous successful defences and later won the IBF title for a second time.
At 18, he was already operating at the top of his division.
5. Pipino Cuevas
Age: 18 years, 6 months
Pipino Cuevas did not even have a particularly intimidating record when he became champion. He had already lost several professional fights.
Then he faced Ángel Espada for the WBA welterweight championship in July 1976 and stopped him in the second round. Cuevas was just 18 years old.
The WBC describes him as the youngest boxer to win a welterweight world championship, and his reign lasted around four years.
He became known for frightening punching power, defending the title repeatedly before eventually running into a young Thomas Hearns.
There are easier ways to lose a belt.
6. Hiroki Ioka
Age: 18 years, 9 months
Before Kazuto Ioka became a four-weight world champion, his uncle Hiroki had already put the family name into boxing history.
Hiroki Ioka beat Mai Thomburifarm in Osaka in October 1987 to become the inaugural WBC strawweight champion. He was only 18.
Ioka later moved up and won the WBA junior-flyweight title as well, proving the first championship was not a freak result.
For context, plenty of elite amateurs have not even made their professional debuts at that age.
Ioka was already defending a world championship.
7. Morris East
Age: 19 years, 1 month
Morris East produced one of the more dramatic title wins on this list.
The Filipino travelled to Tokyo in September 1992 to challenge WBA super-lightweight champion Akinobu Hiranaka.
Hiranaka was ahead. Then East knocked him out in the 11th round.
The finish was later named The Ring’s Knockout of the Year, while East became world champion at only 19.
He also became the youngest Filipino world champion at the time.
That record would become particularly interesting a few years later when another Filipino teenager called Manny Pacquiao started climbing through the sport.
8. Marvin Sonsona
Age: 19 years, 1 month
Marvin Sonsona was another Filipino champion before his 20th birthday.
He beat José López by unanimous decision in Canada in September 2009 to take the WBO junior-bantamweight championship.
Sonsona was just 19 years old. He dropped the experienced López along the way and became one of the youngest Filipino champions ever.
His reign was short-lived after he later failed to make the weight, but the achievement itself remains remarkable.
9. Ben Villaflor
Age: 19 years, 5 months
Ben Villaflor beat Alfredo Marcano over 15 rounds in April 1972 to become WBA super-featherweight champion. He was 19.
Villaflor’s story is different from several fighters above him because he actually developed into a long-term champion.
After losing the belt to Kuniaki Shibata, he won it back by first-round knockout and began a second reign which lasted three years.
He eventually retired at only 23 because of an elbow problem.
By then, he had already fitted an entire championship career into an age when many prospects are only beginning theirs.
10. Al McCoy
Age: 19 years, 5 months
This one takes us back more than a century.
Al McCoy knocked out George Chip in the first round in Brooklyn in April 1914 to claim the recognised middleweight championship.
Boxing looked very different then. There was no WBC, IBF or WBO, and even the WBA’s predecessor had not yet arrived.
Championship lineage was instead established through the recognised champion being beaten in the ring. McCoy did exactly that.
His inclusion also highlights why comparing boxing records across different eras can get messy.
Our guide to boxing’s governing bodies explains how the modern world-title system eventually developed.
How Old Was Manny Pacquiao When He Became World Champion?
Pacquiao narrowly misses the top 10 above.
He was 19 years old when he travelled to Thailand and challenged Chatchai Sasakul for the WBC flyweight championship in December 1998.
Pacquiao was behind on the scorecards. Then he knocked Sasakul out in the eighth round.
That became the first world championship of one of the most remarkable careers boxing has seen.
Pacquiao would eventually win championships across multiple divisions while moving from flyweight all the way into fights at welterweight and beyond.
The teenager who beat Sasakul looked almost nothing like the physically bigger superstar who later faced Oscar De La Hoya, Miguel Cotto and Floyd Mayweather.
How Old Was Mike Tyson When He Became Champion?
Tyson was older than several fighters on this list. His record is famous because of which division he conquered.
On 22 November 1986, Tyson destroyed Trevor Berbick in two rounds to win the WBC heavyweight championship at 20 years, four months and 22 days old.
He remains the youngest heavyweight world champion in boxing history. That record feels particularly difficult to break.
Heavyweights normally take longer to physically mature, and elite fighters at the top of the division tend to have years of professional experience.
Tyson effectively skipped that timetable. Our heavyweight boxing rankings 2026 show just how unusual it is today to find a teenager anywhere near the championship picture.
How Young Was Canelo When He Won His First Title?
Canelo Alvarez was also only 20. He beat Matthew Hatton by unanimous decision in March 2011 to win the vacant WBC super-welterweight championship.
That was just the beginning. Canelo went on to win titles across four divisions and eventually became undisputed at super-middleweight.
It is easy to forget how young he was during the early part of the journey because he had already been fighting professionally for years.
You can follow the latest stage of his career in our Canelo Alvarez next fight guide.
David Benavidez Was a Champion at 20 Too
David Benavidez holds another age record. He was just 20 when he beat Ronald Gavril by split decision in September 2017 to become WBC super-middleweight champion.
That made him the youngest world champion in the division’s history.
Benavidez has since moved considerably higher in weight, showing how unusual it can be to judge a fighter’s eventual physical frame from where they compete as a teenager or young professional.
That is one reason our boxing weight classes matter so much when comparing these records.
Who Is the Youngest Boxing World Champion Ever?
There are two ways I would answer it.
If we follow the WBC’s current recognition across men’s and women’s boxing, Camila Zamorano owns the record, having won its interim atomweight championship at 17 years, five months and 16 days.
If we restrict the question to a full major men’s world championship, the answer remains Wilfred Benítez.
He was only 17 years, five months and 24 days old. That record has survived since 1976.
And when you look at modern boxing, where prospects are often still being carefully developed into their early 20s, somebody beating it would be genuinely extraordinary.
